  • Tamper-evident Boot Update: Making Heads More Usable

    We announced not too long ago that we have successfully integrated the tamper-evident boot software Heads into our Librem laptops. Heads secures the boot process so that you can trust that the BIOS and the rest of the boot process hasn’t been tampered with, but with keys that are fully under your control.

    Heads is cutting edge software and provides a level of security beyond what you would find in a regular computer. Up to this point though, its main user base are expert-level users who are willing to hardware flash their BIOS. The current user interface is also geared more toward those expert users with command-line scripts that make the assumption that you know a fair amount about how Heads works under the hood.

  • Keeper Security Reminds Everyone Why You Shouldn't Use It; Doubles Down On Suing Journalist

    Back in December, we wrote about a blatant SLAPP suit filed by Keeper Security against Ars Technica and its reporter Dan Goodin. Keeper makes a password manager product, and Goodin wrote an article, based on a flaw discovered by Google's Tavis Ormandy. The flaw impacted the browser extension that works with Keeper's application. Keeper took offense to certain elements of the article, and in particular to the idea that Microsoft had forced people to install the flawed software (since the flaw was actually in the browser extension, which is optional). Keeper Security also felt that the article implied that users of its software were vulnerable to a broad attack that put their passwords at risk, when the details suggested it was a more narrow (but still pretty bad) flaw that would require a specific set of circumstances to expose passwords, and there was no evidence that such a set of circumstances existed.

  • New cryptojacking attack uses Redis and NSA exploits to infect machines

    After the script completed the Redis scan, it launches another scan process named “”. This time the new process uses the masscan tool to discover and infect publicly available Windows servers with the vulnerable SMB version.

  • Cyberattack risks mounting for Aussie SMBs: report

    It’s only a matter of time before Australian small businesses are hit hard by a cybersecurity attack but there are things they can do to protect themselves, according to a newly published security report.

Linux Foundation LFCS: Ahmed Alkabary

I always knew about Linux as an alternative to Windows, but never really got to experience it until 2011. I decided to buy a new laptop, and the laptop that stood out for me had Linux pre-installed on it. I remember well the pre-installed distribution was openSUSE. I was hesitant to buy it as I had no experience with Linux whatsoever, but I thought to myself, Well, I can just install windows on it if I don't like it. Once I booted the system and saw how fast and neat everything was, I thought it is a message from the Linux gods. It's really weird because on my first day I felt that Linux was meant for me not just as an operating system to use, but I felt my life will be centered around Linux from that day. Read more

Linux Mint 19 Cinnamon will open apps a lot faster

The Linux Mint development team plans to launch the next version of the popular Linux distribution Linux Mint in the coming months. Linux Mint 19 will be offered in multiple flavors including MATE, Xfce and Cinnamon. If you have used Linux Mint Cinnamon in the past or plan to take it for a test drive in the future, you may benefit from application loading improvements in the upcoming version of Linux Mint. A new blog post on the official Linux Mint blog offers some insight. It all began with a perceived feeling; team members noticed that app loading "felt" faster on MATE or Xfce versions of Linux Mint and slower on Cinnamon versions. Read more

Hands-on with the Raspberry Pi 3 Model B+

The new Raspberry Pi 3 Model B+ was announced and started shipping last week. Of course, I went straight to the good folks at the Swiss and ordered one, which I received the next day. So, the first thing on my to-do list is to congratulate and thank both the Pi Foundation and the for their efficiency in making this new model available immediately after announcement.

  • Linux Foundation announces open source ACRN hypervisor for the Internet of Things
    ACRN's small footprint is partly attributable to the fact that it takes a mere 25,000 lines of code for a hypervisor. There's already involvement from the likes of ADLINK, Aptiv, Intel Corporation, LG Electronics and Neusoft Corporation, and it's likely that many more names will join this list.
  • Linux Foundation Announces ACRN —Open Source Hypervisor for IoT Devices
    The Linux Foundation announced a new project called ACRN (pronounced "acorn") that will provide generic code for the creation of hypervisors for IoT devices. A hypervisor is computer code for creating and running virtual machines. Project ACRN aims to provide a generic structure for an IoT-specific hypervisor component. The Linux Foundation says it built ACRN to be fully-customizable, and as such, the project is comprised of two main components: the hypervisor itself and a device model for interacting with the underlying hardware.
  • Linux Foundation backs new ‘ACRN’ hypervisor for embedded and IoT
    The Linux Foundation has announced a new hypervizor for use in embedded and internet of things scenarios. Project ACRN (pronounced “acorn”) will offer a “hypervizor, and its device model complete with rich I/O mediators.” There’ll also be “a Linux-based Service OS” and the ability to “run guest operating systems (another Linux instance, an RTOS, Android, or other operating systems) simultaneously”.
